TECHNICAL FIELD

The present disclosure generally relates to stable compositions containing a cannabinoid, and more particularly, compositions containing a stable cannabinoid.

BACKGROUND

Cannabinoids (e.g., cannabidiol (CBD), cannabigerol (CBG), etc.) are used in therapeutics, personal care (e.g., skincare, haircare, etc.), health products, or the like. Some of these uses result from the anti-inflammatory and/or antioxidant effects that cannabinoids possess. However, cannabinoids are often sensitive to oxidation and light, resulting in low stability and difficulties in preservation, storage, and transportation, further limiting the application of cannabinoids, especially in personal care. Therefore, it is desirable to provide formulations that can stabilize cannabinoids and stable compositions containing cannabinoids.

DETAILED DESCRIPTION

The following description is presented to enable any person skilled in the art to make and use the present disclosure and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments shown but is to be accorded the widest scope consistent with the claims.

Definitions

As used herein, the term “percentage (i.e., %)” may be by weight of the total composition, unless specifically stated otherwise. The term “ratio” may refer to a weight ratio, unless specifically stated otherwise. The number of significant digits conveys neither a limitation on the indicated amounts nor the accuracy of the measurements. All numerical amounts should be understood to be modified by the word “about” unless otherwise specifically indicated. As used herein, the term “about” and its grammatical equivalents in relation to a reference numerical value and its grammatical equivalents as used herein can include a range of values plus or minus 10% from that value, such as a range of values plus or minus 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2% or 1% from that value. For example, in some embodiments, the amount of “about 10” includes amounts from 9 to 11; in some embodiments, the amount of “about 10” includes amounts from 9.5 to 10.5. All measurements should be understood to be made at 25° C. and at ambient conditions, where “ambient conditions” may refer to conditions under about one atmosphere of pressure and at about 50% relative humidity. All such weights as they pertain to listed ingredients are based on the active level and do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified. All numeric ranges are inclusive of narrower ranges and combinable; delineated upper and lower range limits are interchangeable to create further ranges not explicitly delineated.

The terms “actives” and “active component(s)” may refer to compound(s) that, when applied to a target object, provide a benefit or improvement to the target object. The target object herein may include a user or a portion thereof (e.g., keratinous tissue of the user, a target region of the keratinous tissue, tooth, or the like, or any combination thereof. As used herein, the term “keratinous tissue” may refer to keratin-containing layers disposed as the outermost protective covering of mammals which includes, but is not limited to, skin, hair, nails, cuticles, etc. Accordingly, the actives and/or active component(s) herein may be used for skincare, haircare, fingernail care, oral care, the like, or any combination thereof.

The term “apply” or “application,” as used in reference to a composition, may refer to applying or spreading the composition onto a skin surface (such as the epidemics), the hair, a surface of a fingernail, the surface of the tooth, etc. of the user.

The term “derivative” may refer to a molecule similar to that of another one, but differing from it with respect to a certain functional moiety (e.g., esters, ethers, amides, amines, carboxylic acids, hydroxyls, acetyls, thiols, halogens, thiols, and/or salt derivatives of the relevant molecule).

The term “dermatologically acceptable” may refer to that the compositions or components thereof are suitable for use in contact with mammalian keratinous tissue without undue toxicity, incompatibility, instability, allergic response, and the like.

The term “effective amount” may refer to an amount of a compound or composition sufficient to significantly induce a positive benefit to keratinous tissue, such as health, appearance, and/or feel benefit, including, independently or in combination, the benefits disclosed herein, but low enough to avoid serious side effects (i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan). An effective amount of a cannabinoid may be an amount sufficient to regulate a desired condition of mammalian keratinous tissue when topically applied thereto in a composition (e.g., a personal care composition) over the course of a treatment period.

The “personal care composition” may refer to a topical composition for regulating a condition of mammalian keratinous tissue (e.g., skin, hair, fingernails) and/or tooth. Exemplary personal care compositions may include skin creams, lotions, and serums; shave prep compositions; body washes; deodorants and antiperspirants, shampoos; conditioners; toothpaste, mouthwashes; or the like, or any combination thereof. As used herein, the term “regulating the condition of mammalian keratinous tissue and/or tooth” may refer to improving the appearance and/or feel of keratinous tissue and/or tooth.

The term “topical” may refer to a composition that is intended to be applied to a bodily surface such as skin or hair.

The term “cannabinoid containing compositions (e.g., personal care products)” may refer to any compositions that contain a cannabinoid. Preferred compositions may include compositions used for regulating the condition of the skin, even more preferably reducing the appearance of skin aging, reducing the appearance or occurrence of skin acne, and/or treating skin acne. The cannabinoid containing compositions herein may also exhibit an absence of significant (e.g., consumer-unacceptable) skin irritation and good aesthetics.

The term “signs of skin aging” may include, but is not limited to, all outward visibly and tactilely perceptible manifestations as well as any other macro or micro effects due to skin aging. Such signs may be induced or caused by intrinsic factors or extrinsic factors, e.g., chronological aging and/or environmental damage. These signs may result from processes that include, but are not limited to, the development of textural discontinuities such as wrinkles and coarse deep wrinkles, skin lines, crevices, bumps, large pores (e.g., associated with adnexal structures such as sweat gland ducts, sebaceous glands, or hair follicles), or unevenness or roughness, loss of skin elasticity (loss and/or inactivation of functional skin elastin), sagging (including puffiness in the eye area and jowls), loss of skin firmness, loss of skin tightness, loss of skin recoil from deformation, discoloration (including undereye circles), blotching, sallowness, hyperpigmented skin regions such as age spots and freckles, keratoses, abnormal differentiation, hyper keratinization, elastosis, collagen breakdown, and other histological changes in the stratum corneum, dermis, epidermis, the skin vascular system (e.g., telangiectasia or spider vessels), and underlying tissues, especially those proximate to the skin.

The term “stable,” when referring to a cannabinoid contained in a composition (e.g., a personal care composition), may refer to less than 45% (e.g., less than 25%, 20%, 15%, 10%, or even less than 5%) of the cannabinoid present in the composition degrades (i.e., chemically converted to a different compound via, for example, oxidation or some other chemical process) when the composition is subjected to environmental conditions commonly experienced or conditions that are used for assessing stability by compositions of the type (e.g., ambient temperature, 30° C., 35° C., or 40° C. for 2 or more weeks, 1 month or more, 2 months or more, or 3 months or more). In some embodiments, the cannabinoid contained in the composition may be stable at 45° C. for more than 2, 4, or even 8 weeks. A suitable method of determining cannabinoid stability may include a high performance liquid chromatography (HPLC) method.

Before the present discovery, stabilizing a cannabinoid (e.g., CBD, CBG, etc.) in compositions (e.g. solution or cosmetic composition) at room temperature was problematic. Taking CBD as an example, the stability of CBD may be influenced by multiple factors (e.g., temperature, oxidation, light, solvent, etc.). For example, CBD may be highly unstable at room temperature, while CBD may be relatively stable at 5° C. or lower temperature. As another example, CBD may be highly unstable in oxidizing and/or light environments, while CBD may be relatively stable when CBD is protected from oxidization and light. As still another example, CBD may be more stable in the solvent of non-aqueous medium (e.g., ethanol) than in the solvent of aqueous medium. As still another example, 10% of CBD may be degraded within 24 hours in a simulated physiological condition (PH 7.4 and 37° C.). The above descriptions may indicate that CBD is highly unstable, which needs to be taken into count in the development of compositions and products containing CBD.

The present disclosure provides compositions containing a cannabinoid exhibiting good stability. In order to measure the stability of a product, a certain stability criteria may be established. The certain stability criteria may be based on a percentage of cannabinoids (by mass) remaining in a composition or product after a given time at a given temperature. For example, if a cannabinoid is added to a product at 0.1%, and 0.0879% of the cannabinoid remained after three weeks of storage at 45° C., then such a product may be said to have retained 87% of the original cannabinoid after three weeks storage at 45° C.

Stability tests, such as shelf-life tests, may also be used to evaluate the stability of a composition (e.g., a personal care composition). For example, in order to evaluate the stability of a cannabinoid in a given composition, the composition may be placed in a container that limits the free flow of oxygen (e.g., an aluminum tube, laminated tube, glass jar, HDPE jar, PP jar, HDPE pump) and stored fora given time (e.g., 12 weeks) at a given temperature (e.g., constant 45° C.). The percentage loss of a cannabinoid may be measured after an elapsed time period.

Compositions

In the present disclosure, a composition having improved the stability of a cannabinoid is provided. The composition may include a cannabinoid, a lipid, water, an emulsifier, or the like. The composition may be an oil-in-water composition/formulation, such that the cannabinoid contained in the composition may be stable in environmental conditions and/or applied on mammalian keratinous tissue (e.g., skin, hair, fingernails) and/or tooth of the user. The cannabinoid may include CBD, CBG, or the like, or any combination thereof. For example, the cannabinoid may include only CBD or CBG. As another example, the cannabinoid may include a mixture of CBD and CBG.

In some embodiments, the composition (also referred to as a first composition) may be in the form of a stable Nano lipid carrier. The stable Nano lipid carrier may refer to that the cannabinoid remained in the first composition after three months of storage at 45° C. and in light may be greater than 55% by weight of the original cannabinoid in the first composition. In some embodiments, the cannabinoid may be at 0.05%-0.5% by weight of the first composition. For example, the cannabinoid of the first composition by weight may be at 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, etc. In some embodiments, the lipid may be at 0.026%-15% by weight of the first composition. For example, the lipid of the first composition may include a liquid lipid and a solid lipid. The liquid lipid may include triglyceride, carbonate, long chain straight alkane, isosorbide derivatives (e.g., isosorbitan or isosorbide ether), or the like, or any combination thereof. The solid lipid may include fatty alcohol ester, vegetable wax, or the like, or any combination thereof. The liquid lipid of the first composition by weight may be at 0.01%-5%. The solid lipid of the first composition by weight may be at 0.016%-10%. In some embodiments, the emulsifier may be at 0.02%-20% by weight of the first composition. For example, the emulsifier of the first composition by weight may be at 0.02%, 0.1%, 0.5%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, etc. The emulsifier may include polypropylene glycol (PPG) polyether, polyglycerol fatty acid ester, or the like, or any combination thereof. In some embodiments, the weight ratio of the emulsifier to the lipid in the first composition may be (0.4-3.5):1. For example, the weight ratio of the emulsifier to the lipid in the first composition may be 0.4:1, 0.5:1, 0.9:1, 1:1, 1.5:1, 2:1, 2.5:1. 3:1, 3.5:1, etc. In some embodiments, the first composition may further include optional ingredients as described elsewhere in the present disclosure, e.g., including a thickening agent, a phenol, a perfume, a coloring agent, an active component, or the like, or any combination thereof. For example, the first composition may consist of the cannabinoid, the liquid lipid, the solid lipid, the emulsifier, the water, and the thickening agent. As another example, the first composition may consist of the cannabinoid, the liquid lipid, the solid lipid, the emulsifier, the water, and one or more active components.

In some embodiments, the first composition may be prepared according to the following operations. A first liquor may be obtained by melting, at a preset temperature, the solid lipid, the liquid lipid, and the emulsifier. The preset temperature may be 50° C. to 95° C. For example, the preset temperature may be 50° C., 55° C., 60° C. 65° C., 70° C., 80° C., 80° C., 85° C., 90° C., 95° C., etc. A second liquor may be obtained by mixing the cannabinoid and the first liquor. The second liquor may be in a water-in-oil form. A third liquor may be obtained by mixing the water at the preset temperature and the second liquor. The third liquor may be in an oil-in-water form. A Nano lipid carrier may be obtained by cooling the third liquor to room temperature. It should be noted that conditions (e.g., the temperature or order of the operations) of the preparation process may be adjusted according to different situations, which is not limiting.

In some embodiments, the composition (also referred to as a second composition) may be in the form of a stable oil-in-water (O/W) emulsion. The stable O/W emulsion may include a continuous aqueous phase, which typically includes water, water-miscible liquids, and/or water-soluble materials, and a dispersed hydrophobic phase, which typically includes lipids, oils, and/or oily materials. The O/W emulsions herein may include 1% to 50% (e.g., 1% to 30%) by volume of the dispersed hydrophobic phase and 1% to 98% (e.g., 40% to 90%) by volume of the continuous hydrophilic phase. The emulsion may also include a gel network, such as described in G. M. Eccleston, Application of Emulsion Stability Theories to Mobile and Semisolid OAV Emulsions, Cosmetics & Toiletries, Vol. 101, November 1996, pp. 73-92.

The second composition may include a dermatologically acceptable carrier that enables other components (e.g., actives) to be delivered to the skin at an appropriate concentration. The dermatologically acceptable carrier may thus act as a diluent, dispersant, solvent, or the like for particulate material, which helps ensure that it can be applied to and distributed evenly over the selected target at an appropriate concentration. The dermatologically acceptable carrier may contain one or more dermatologically acceptable solid, semi-solid or liquid fillers, diluents, solvents, extenders, and the like. The dermatologically acceptable carrier may be solid, semi-solid, or liquid. In some instances, the carrier can be inert or it can provide benefits of its own to keratinous tissue. Concentrations of the dermatologically acceptable carrier can vary with the carrier selected and the intended concentrations of the composition components.

The type of the dermatologically acceptable carrier utilized in the present personal care composition depends on the type of product form desired for the composition. The topical composition useful in the present disclosure may be made into a wide variety of product forms such as are known in the art. The product forms may include, but are not limited to, lotions, creams, gels, sticks, sprays, ointments, pastes, mousses and cosmetics (e.g., solid, semi-solid, or liquid makeup, including foundations, eye-makeup, pigmented or non-pigmented lip treatments, e.g., lipsticks, and the like). The product forms may comprise several types of dermatologically acceptable carriers including, but not limited to, solutions, aerosols, emulsions, gels, solids, and liposomes.

The dermatologically acceptable carriers herein may contain a dermatologically acceptable, hydrophilic diluent. As used herein, “diluent” may include materials in which the particulate material of the composition can be dispersed, dissolved, or otherwise incorporated. Nonlimiting examples of hydrophilic diluents are water, organic hydrophilic diluents such as lower monovalent alcohols (e.g., C₁-C₄) and low molecular weight glycols and polyols, including propylene glycol, polyethylene glycol (e.g., Molecular weight 200-600 g/mole), polypropylene glycol (e.g., Molecular Weight 425-2025 g/mole), glycerol, butylene glycol, 1,2,4-butanetriol, sorbitol esters, 1,2,6-hexanetriol, ethanol, isopropanol, sorbitol esters, butanediol, ether propanol, ethoxylated ethers, propoxylated ethers, or the like, or any combination thereof. Water is a particularly suitable diluent. For example, the second composition may include about 60% to about 99.99% of the hydrophilic diluent.

The second composition may be made by conventional methods of making personal care compositions comprising an O/W emulsion system, which are known to those skilled in the art. In some embodiments, the second composition may include the cannabinoid, the lipid, the water, the emulsifier, an oil, and a fatty alcohol. The lipid (and/or the oil) and the water in the second composition may help to form an O/W emulsion. In some embodiments, the cannabinoid in the second composition may be stable. For example, less than 25% (e.g., less than 20%, 15%, less than 10%, etc.) of the cannabinoid in the second composition may be lost (i.e., degraded) between the time the second composition is packaged by the manufacturer and the time the package is first opened by a consumer. A suitable method for determining the amount of cannabinoid loss may include an HPLC method.

In some embodiments, the cannabinoid may be at 0.0001% to 2% (e.g., 0.005% to 2%, 0.01% to 1%, 0.01% to 0.5%) by weight of the second composition. For example, the cannabinoid of the second composition by weight may be at 0.05% to 0.5%. The cannabinoid of the second composition may be one cannabinoid (e.g., CBD or CBG) or a mixture of more than one cannabinoid (e.g., a mixture of CBD and CBG).

In some embodiments, the oil may be at 1% to 50% by weight of the second composition. The oil in the second composition may be with a hydrophile-lipophile balance (HLB) value of between 6 and 11.5. The HLB value of the oil may help to ensure that the cannabinoid and other oil-soluble actives are fully soluble in the oil and to help maintain proper portioning of the oil droplets in the O/W emulsion. In some embodiments, the oil may be an emollient (i.e., a water-immiscible, oily or waxy material used to increase the occlusive properties of skin), but need not necessarily be. It is believed, without being limited by theory, that certain oils can help stabilize the cannabinoid in an O/W emulsion by increasing cannabinoid partitioning in the oil droplets of the internal phase, thereby reducing the interaction between the cannabinoid and water present in the continuous phase of the emulsion. Thus, it may be important to ensure that a suitable amount of oil is present in the second composition and the ratio of oil relative to other ingredients is within a particular range. For example, the weight ratio of the oil to the cannabinoid in the second composition may be (5-50):1 (e.g., (15-35):1, (18-30):1).

In some embodiments, the oil in the second composition may include capric/caprylic triglyceride, coconut oil, argan oil, avocado oil, jojoba oil, moringa oil, soybean oil, Butyrospermum parkii (shea) nut extract, Vitis vinifera (grape) seed oil, Crambe abyssinica seed oil, Raphanus sativus (radish) seed extract, Argania spinose kernel oil extract, Limnanthes alba (meadowfoam) seed oil, Triticum vulgare (wheat) germ oil, Olea europaea (olive) fruit oil, hydrogenate vegetable oils, shea butter ethyl esters, canola oil, c10-18 triglyceride, hydrogenate palm oil, hydrogenate coco-glyceride, Cucurbita pepo (pumpkin) seed oil, Sunflower seed oil, rose hip oil, safflower oil, tea tree oil, lavender oil, flaxseed oil, isoamyl cocoate, phenoxyethyl caprylate, pentaerythrityl tetraethylhexanoate, pentaerythrityl tetraisostearate, glycereth-5 lactate, c12-15 alkyl benzoate, bis-phenylpropyl dimethicone, cyclopentasiloxane, octyldecanol, hexyldecanol, heptyl undecylenate, dimyristyl tartrate, hydrogenate polydecene, propylene glycol ricinoleate, peg-7 cocoate, decyltetradecanol, isopropyl lauroyl sarcosinate, octyldodecyl myristate, diisooctyl adipate, diisostearyl malate, hydrogenate castor oil, squalane, isohexadecane, ppg-15 stearyl ether, isopropyl myristate, phenyl trimethicone, propandiol diisostearate, dimethicone, dicaprylyl ether, octyl salicylate, isopropyl isostearate, or the like, or any combination thereof.

In some embodiments, the emulsifier contained in the second composition may help to stabilize the O/W emulsion. The emulsifier may be nonionic, anionic, or cationic. In some embodiments, the emulsifier may include cetearyl glucoside, cetearyl alcohol, or the like, or any combination thereof. In some embodiments, the emulsifier may be at 1% to 10% (e.g., 2% to 5%) by weight of the second composition. The amount and type of the emulsifier selected for use in the second composition may vary based on the type and amount of the oil in the second composition. For example, the second composition may have a ratio of the oil to the emulsifier of between (4-50):1 (e.g., (5-30):1, (10-20):1, (10-15):1, etc.).

In some embodiments, the fatty alcohol contained in the second composition may function as an emollient, emulsifier, thickener, structural agent, and/or carrying agent for oil soluble ingredients in the composition. The fatty alcohol may include cetyl alcohol, stearyl alcohol, cetearyl alcohol, behenyl alcohol, arachidyl alcohol, lignocaryl alcohol, or the like, or any combination thereof. It is believed, without being limited by theory, that the combination of emulsifier, fatty alcohol, and solvent creates a lamellar liquid crystal gel network in which the droplets of cannabinoid/oil are formed. Thus, it may be important to provide a suitable ratio of emulsifier to fatty alcohol in the second composition to produce a stronger lamellar gel-network/liquid crystal that makes less water available to react with the cannabinoid. For example, a weight ratio of the fatty alcohol to the emulsifier may be between 1:1 and 11:1 (e.g., between 5:3 and 10:1).

In some embodiments, the second composition may include a water-swellable material that acts to bind the water in the second composition. By binding some of the water in the second composition the interaction between the water and the cannabinoid may be reduced. The water-swellable material in the second composition may be natural or synthetic (e.g., water-swellable clay and superabsorbent polymers). The water-swellable material may be at 0.01% to 5% by weight of the second composition.

In some instances, the water-swellable material may be a superabsorbent polymer (“SAP”) present in the aqueous phase of the second composition as a multitude of particles. When swollen, the SAP may provide a light, cool, and silky feel during the application of the second composition. The SAP particles may have a dry, number-average particle size of 100 μm or less (e.g., 50 μm or less), for example, 2 μm to 100 μm, with a median particle size of 25, or even in the range of 2 μm to 40 μm with a median particle size of 12 μm. The SAP particles may have a water-absorbing capacity ranging from 20 to 2000 times their own weight (i.e., 20 g to 2000 g of water absorbed per gram of absorbent polymer), for example, 30 to 1500 times, 50 to 1000 times, or even 400 times. The water-absorbing characteristics of the SAP particles herein may be defined at standard temperature and pressure conditions for distilled water. For example, the value of the water-absorbing capacity of SAP herein may be determined by dispersing 0.5 g of polymer(s) in 150 g of distilled water, waiting 20 minutes, filtering the non-absorbed solution through a 150 μm filter for 20 minutes, and weighing the non-absorbed water to determine how much was absorbed by the polymer. %). In some instances, the viscosity of an SAP solution in 1% distilled water is in the range of 20 to 30 Pas (e.g., 22 to 29 Pas) at pH 4 and in the range of 23 to 28 Pas at pH 7. Once hydrated, the SAP particles in the second composition may swell to form relatively soft beads that have a number average diameter of 10 μm to 150 μm (e.g., 20 μm to 130 μm, 30 μm-120 μm, 40 μm-100 μm, 50 μm-90 μm, or even about 70 μm).

In some embodiments, the first or second composition may include a variety of optional ingredients (e.g., active components) that are known for use in personal care composition, as long as the optional ingredient(s) do not unduly alter product stability, aesthetics, or performance. The optional ingredients, when incorporated into the first or second composition, should be suitable for contact with human keratinous tissue without undue toxicity, incompatibility, instability, allergic response, and the like within the scope of sound judgment. The optional ingredients may be from about 0.0001% to about 50%; from about 0.001% to about 20%; from about 0.01% to about 10%; etc., by weight of the first or second composition. The optional ingredients may include abrasives, absorbents, opacifying agents, colorings/colorants (e.g., pigments, dyes, and lakes), particles, essential oils, anti-caking agents, foaming agents, anti-foaming agents, oil control agents, binders, biological additives, vitamins, minerals, peptides, sugar amines, flavonoid compounds, anti-oxidants, preservatives, phytosterols, protease inhibitors, tyrosinase inhibitors, exfoliating agents, skin lightening agents, sunless tanning agents, thickeners, pH adjusters, anti-acne actives, anti-cellulite actives, anti-wrinkle actives, phytosterols and/or plant hormones, N-acyl amino acid compounds, antimicrobials, antifungals, moisturizers, emollients, hum ectants, lubricating agents, fragrances, anti-dandruff agents, buffering agents, bulking agents, chelating agents, biocides, denaturants, astringents, external analgesics, anti-inflammatory agents, sunscreen agents, film formers and/or polymers for aiding film-forming properties and substantivity of the composition, propellants, reducing agents, sequestrants, conditioning agents, or the like, or any combination thereof. For example, the optional ingredient(s) of the second composition may include vitamins, proteins, zeolites, peptides, skin-lightening, sunscreen actives, terpene alcohols, desquamation actives, antiacne actives, anti-wrinkle actives, anti-atrophy actives, anti-oxidants, flavonoids, anti-inflammatory agents, anti-cellulite agents, tanning actives, skin-soothing actives, skin healing actives, conditioning agents, or the like, or any combination thereof.

In some embodiments, the first composition and/or the second composition may be useful for regulating the condition of skin and/or hair while maintaining good stability. Regulating a condition of the skin may include reducing the appearance of fine lines and/or wrinkles on the skin, reducing the appearance of eye bags and dark circles under the eyes, sagging skin, scars/marks, dimples, pores, stretch marks, roughness, skin surface blemishes, frown lines, expression lines, rhytides, blemishes, photodamage, crevices, and/or unevenness. Regulating the condition of the skin also includes reducing the occurrence and/or appearance of acne, treating acne, or the like.

The use of the first and/or second composition may include identifying a target portion of keratinous tissue (e.g., a facial skin surface such as the forehead, perioral, chin, periorbital, nose, and/or cheek) in need of treatment and/or where treatment is desired; and applying a safe and effective amount of the first and/or second composition to the target portion of tissue. Without intending to be bound by theory, it is believed that the application of an effective amount of the first and/or second composition to a target portion of keratinous tissue in need of treatment or where treatment is desired can provide the desired appearance benefit over the course of a treatment period.

The treatment period should be of sufficient time for the component(s) in the first and/or second composition to provide the desired benefit to the target portion of keratinous tissue (e.g., improve appearance, increase moisturization, etc.). The treatment period may last for at least 1 week (e.g., about 2 weeks, 4 weeks, 8 weeks, or even 12 weeks). For example, the treatment period may extend over multiple months (i.e., 3-12 months) or multiple years. As another example, the first and/or second composition may be applied most days of the week (e.g., at least 4, 5, or 6 days a week), at least once a day, or even twice a day during a treatment period of at least 2 weeks, 4 weeks, 8 weeks, or 12 weeks.

The step of applying the first and/or second composition may be accomplished by localized application. In reference to the application of a composition, the terms “localized,” “local,” or “locally” may refer to that the composition is delivered to the targeted area (e.g., a hyperpigmented portion of the skin) while minimizing delivery to keratinous surfaces where treatment is not desired. For example, the first and/or second composition may be applied and lightly massaged into an area of skin. The form of the first and/or second composition or the dermatologically acceptable carrier should be selected to facilitate localized application. While certain embodiments herein contemplate applying a composition locally to an area, it should be noted that compositions herein may be applied more generally or broadly to one or more skin surfaces.

The first and/or second composition may be applied in a variety of manners, including by rubbing, wiping, or dabbing with hands or fingers, or by an implement and/or delivery enhancement device. Exemplary implements may include a sponge or sponge-tipped applicator, a swab (for example, a cotton-tipped swab), a pen optionally comprising a foam or sponge applicator, a brush, a wipe, or the like, or any combination thereof. Exemplary delivery enhancement devices may include magnetic, mechanical, electrical, ultrasonic, and/or other energy devices. For example, the first and/or second composition may be spread onto the skin to facilitate the separation of the aqueous phase from the oil phase. When the aqueous and oil phases have separated, the first and/or second composition may be left on the keratinous tissue. Alternatively, the first and/or second composition may be allowed to remain on the skin for 5 seconds, 10 seconds, 30 seconds, or 1 minute before being rubbed into the keratinous tissue.

In some embodiments, the composition (also referred to as a third composition) may be in the form of a stable cosmetic composition. The third composition (i.e., the stable cosmetic composition) may include one or more cannabinoids, an emulsifier, a stabilizing agent which includes an antioxidant, etc. Under the action of the stabilizing agent, the cannabinoid(s) remained in the third composition after three months of storage at 45° C. and in light may be greater than 80% (e.g., 85%, 87%, 91%, etc.) by weight of the original cannabinoid(s) in the third composition.

In some embodiments, the one or more cannabinoids may be at 0.05%-10% in total by weight of the third composition. For example, the one or more cannabinoids of the third composition may be at 0.05%-5% (e.g., 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 1%, 2%, 3%, 4%, 5%, etc.) in total by weight of the third composition. As another example, the one or more cannabinoids of the third composition may be at 1%-3% (e.g., 1%, 1.5%, 2%, 2.5%, 3%, etc.) in total by weight of the third composition. In some embodiments, the one or more cannabinoids may include cannabidiol (CBD), cannabigerol (CBG), or a derivative thereof. For example, the third composition may include CBD and CBG which are at 2% in total by weight of the third composition. For instance, the third composition may include CBD at about 1% by weight of the third composition and CBG at about 1% by weight of the third composition.

In some embodiments, the emulsifier may be at 0.02%-20% by weight of the third composition. For example, the emulsifier may be at 1%-10% by weight of the third composition. As another example, the emulsifier may be at 1%-5% by weight of the third composition. For instance, the emulsifier may be at 0.02%, 0.1%, 0.5%, 1%, 1.5%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, etc., by weight of the third composition. In some embodiments, the emulsifier may include cetyl alcohol, cetearyl alcohol, behenyl alcohol, stearic acid, stearyl alcohol, glycerin, polypropylene glycol (PPG) polyether, polyglycerol fatty acid ester, cetearyl olivate, sorbitan olivate, lecithin, PEG-7 Glyceryl Cocoate, or the like, or any combination thereof.

In some embodiments, the antioxidant may be at 0.01%-2% by weight of the third composition. For example, the antioxidant may be at 0.05%-1% by weight of the third composition. In some embodiments, the antioxidant may include pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate (PTDTBH), butylated hydroxytoluene (BHT), propyl gallate, or the like, or any combination thereof. For example, the third composition may include PTDTBH at 0.01-0.2% by weight of the third composition. As another example, the third composition may include PTDTBH at about 0.2% by weight of the third composition. As still another example, the third composition may include BHT at about 1% by weight of the third composition. As further another example, the third composition may include propyl gallate at about 0.05-0.2% by weight of the third composition.

In some embodiments, the third composition may further include a vitamin, a liquid lipid, a solid lipid, a moisturizing agent, a thickener, a fragrance, a coloring agent, an absorbent, a preservative, or other active agents, or any combination thereof. The vitamin may be selected from the group consisting of vitamin A, vitamin B, vitamin C, vitamin E, vitamin H, vitamin K, etc. The liquid lipid may be selected from the group of triglyceride, carbonate, long chain straight alkane, isosorbide derivatives (e.g., isosorbitan or isosorbide ether), etc. The solid lipid may be selected from the group consisting of fatty alcohol ester, vegetable wax, beeswax, etc. The moisturizing agent (e.g., a humectant, an emollient, etc.) may be selected from the group consisting of glycerin, squalane, alpha-hydroxy acids (AHAs), hyaluronic acid, amino acid, collagen, ceramide, etc. The thickener may be selected from the group consisting of polyacrylate crosspolymer-6, polysaccharides, proteins, alcohols, silicones, waxes, etc. The fragrance may be selected from the group consisting of perfume, cologne, aftershave, etc. The coloring agent (e.g., a dye or a pigment) may be selected from the group consisting of fluorescein, quinoline, triphenylmethane, titanium dioxide, iron oxide, chromium oxide, organic colorants, particles of silver and gold, etc. The absorbent may be selected from the group consisting of sodium polyacrylate, kaolin, talc powder, magnesium oxide, etc. The preservative may be from the group consisting of phenoxyethanol, ethylhexyl glycerin, caprylhydroxamic acid, caprylyl glycol, etc. In some embodiments, the liquid lipid may be at 0.01%-5% by weight of the third composition. The solid lipid may be at 0.016%-10% by weight of the third composition. It should be noted that the third composition may also include any other active ingredients, which are not limited herein.

Merely by way of example, the third composition may include CBD at 0.5%-1.5% (e.g., 1%) by weight of the third composition, CBG at 0.5%-1.5% (e.g., 1%) by weight of the third composition, an emulsifier at 0.1%-5% by weight of the third composition; and a stabilizing agent comprising PTDTBH at 0.05%-0.5% (e.g., 0.1%) by weight of the third composition, or BHT at 0.5%-2% by weight of the third composition. The emulsifier at 1%-5% by weight of the third composition may include cetyl alcohol at 0.5%-1.5% by weight of the third composition, and the third composition may further include water at about 75%-85% by weight of the third composition, glycerin at about 2.5%-3.5% by weight of the third composition, dicaprylyl carbonate at about 2.5%-3.5% by weight of the third composition.

According to some embodiments of the present disclosure, both CBD and CBG are included in the cosmetic composition (i.e., the third composition), and the presence of both CBD and CBG may improve the comprehensive effectiveness of the cosmetic composition. In some embodiments, a weight ratio of CBD and CBG is 1:1; such a ratio would be suitable for some formula, making the cosmetic composition more balanced in terms of anti-inflammatory and/or antioxidant effects than a cosmetic composition including only CBD, only CBG, or both CBD and CBG with other weight ratios. For example, in some embodiments, each of the CBD and CBG, at an ideal level, may be 1% by weight of the cosmetic composition. In addition, by adding the stabilizing agent in the cosmetic composition, the cannabinoids (e.g., CBD and CBG) in the cosmetic composition can be protected from being oxidized or the oxidization rate of the cannabinoids (e.g., CBD and CBG) in the cosmetic composition can be significantly reduced, thereby making the cosmetic composition more stable. PTDTBH would be one of the optimal stabilizing agents for stabilizing the cannabinoids in the cosmetic composition. PTDTBH at a level greater than 0.05% (e.g., at 0.1%, 0.2%), especially at 0.2%, by weight in the cosmetic composition may improve the stability of the cannabinoids in the cosmetic composition to a desired extent. In some embodiments, besides the CBD, CBG, and the stabilizing agent, the cosmetic composition would be added with any other different active agents as well as the active agents do not affect or affect as little as possible the function of the stabilizing agent for the CBD and/or CBG in the cosmetic composition, which further improves the comprehensive effectiveness of the cosmetic composition.

Stability Test Method

The present disclosure provides an HPLC method which is a suitable manner for determining the loss of cannabinoids in a composition, which reflects the stability of the cannabinoids in the composition.

A sufficient quantity of a test composition (e.g., the first composition or the second composition) is placed in a controlled environment chamber/room set at a preset temperature (e.g., 45° C.) for a preset time (e.g., 1 month). After the preset time, the composition is removed from the controlled environment.

The stability of cannabinoids in the test composition is determined on a % w/w basis by HPLC (isocratic elution) as follows. The HPLC column(s) is conditioned in accordance with conventional practices.

Chromatographic Conditions

1. Column: C18 (5 microns), 150 mm×4.6 mm

2. Mobile Phase (Eluent): a mixture of methanol, acetonitrile, and water (52:30:18 v/v)

3. Column temperature: approximately 25° C. (Ambient)

4. UV wavelength: 228 nm

5. Injection volume: 20 microliters

6. Flow rate: 1.8 ml/min

7. Run time: approximately 6 minutes

8. Cannabinoid retention time: approximately 5 minutes (e.g., 4.72 minutes)

Mobile Phase Preparation

1 L of Mobile Phase (Eluent) is prepared by mixing 520 mL of methanol, 380 mL of acetonitrile, and 180 mL of water, adjusting the mixture to a pH of 4.5 with acetic acid, and further filtering the adjusted mixture through a membrane filter (47 mm membrane, 0.45 μm pore size, nylon) and degassed in an ultrasonic bath before use.

External Standard Preparation (prepare fresh on the day of use)

A reference standard solution of cannabinoids in methanol (1 mg/mL) is prepared by dissolving 25 mg of cannabinoids the same as that contained in the test composition in 25 mL of methanol without being exposed to light. Concentrations between 1-150 μg/m L are prepared by transferring a 5 mL aliquot of the reference standard solution to a 50 mL amber flask and diluting to volume with the mobile phase.

HPLC Sample Preparation

The test composition is mixed with ethanol thoroughly before testing according to a preset concentration (100 μg/m L). The mixed composition is stored at −20° C. without being exposed to light. Before use, approximately 1 ml of the mixed composition is filtered into an auto-sampler vial using a syringe filter.

(A)/(B)×(B)/(W)×(DF)×100=cannabinoid,% w/w

where, A=peak area of cannabinoid for the sample, B=peak area of cannabinoid for the calibration, C=cannabinoid standard weight in mg, W=sample weight, mg, DF=Dilution Factor (e.g., 0.1).

The present disclosure also provides stability tests for CBD/CBG, which can reflect the stability of the cannabinoids in a cosmetic composition (e.g., the third composition).

Seven samples were prepared for the stability tests. The seven samples to be tested were composed of the same base formula with different levels, CBD and/or CBG with the same level, and antioxidants with different types and/or levels. A positive control sample was also prepared composed of the same base formula and CBD and CBD without a stabilizing agent and the CBD and CBG were at the same levels as that in the seven samples. The seven samples (i.e., S1-S7) and the positive control sample (i.e., S8) are listed as follows, illustrating the levels of ingredient s by weight in the samples.

	S1	S2	S3	S4	S5	S6	S7	S8

The seven samples S1-S7 were put in stability in glass jars for 3 months in an oven (45° C.) to obtain seven processed samples 51′-S7′. During the 3 months, the seven samples S1-S7 were checked in color every week. The sample S1 showed a color change after 1 week. Samples S2 and S4 showed slight color changes after 1 week. Samples S3, S5, S6, and S7 showed no color change (or no obvious color change) even after 9 weeks. Accordingly, CBD and CBG in the samples S3, S5, S6, and S7 are indicated to be more stable than that in the samples S1, S2, and S4.

FIGS. 1-7 show images of the processed samples 51′-S7′ with an image of the positive control sample S8 respectively. As shown, the positive control sample S8 was white, which indicates that the positive control sample is not or substantially not oxidized. The original colors of the samples S1-S7 were close to the color of the positive control sample. Each of the processed samples 51′-S7′ was compared with the positive control sample S8 in color. If a processed sample of the processed samples S1′-S7′ is darker than the positive control sample, the processed sample may be determined to be oxidated after 3 months. The more the color difference between the processed sample and the positive control sample S8 is, the less stable CBD and CBG in the processed sample may be. As shown in FIGS. 1-7, the color differences between the processed sample S1′-S7′ and the positive control sample S8 can be ranked in descending order as: the color difference between S1′ and S8>the color difference between S4′ and S8>the color difference between S2′ and S8>the color difference between S3′ and S8>the color difference between S5′ and S8>the color difference between S6′ and S8>the color difference between S7′ and S8. Accordingly, CBD and CBG in the samples with PTDTBH are more stable, and the more PTDTBH a sample contains, the more stable CBD and CBG in the sample may be.

In addition, the processed sample S4′ and the processed sample S7′ were measured using a GC-MS device (GC-7890A and MSD-5975C produced by Agilent Technologies) according to the analyzed test provided in “Aviv, Amirav, et al. Cannabis and its cannabinoids analysis by gas chromatography-mass spectrometry with Cold EI. March 2021 Journal of Mass Spectrometry 56(6)” to determine levels of CBD and CBG in the processed samples S4′ and S7′. The measurement results are shown as follows.

The measurement result of the processed sample S4′

	Analyte	LOQ (limit of quantitation)	Mass (%)
	THCa	0.08	ND

	CBN	0.04	ND
	CBGa	0.08	ND
	CBG	0.04	0.79
	CBC	0.04	ND
	Total	—	1.60

It can be seen from the measurement result of the processed sample S4′, under the action of grape oil and olive oil, CBD and CBG remained in the processed sample S4′ after three months of storage at 45° C. and in light is equal to 80% by weight of the original CBD and CBG in the sample S4.

The measurement result of the processed sample S7′

	Analyte	LOQ (limit of quantitation)	Mass (%)
	THCa	0.08	ND
	Δ9-THC	0.04	ND
	Δ8-THC	0.04	ND
	THCV	0.04	ND
	CBDa	0.08	ND
	CBD	0.04	0.91
	CBDV	0.04	ND
	CBN	0.04	ND
	CBGa	0.08	ND
	CBG	0.04	0.85
	CBC	0.04	ND
	Total	—	1.75

It can be seen from the measurement result of the processed sample S7′, under the action of PTDTBH, CBD and CBG remained in the processed sample S7′ after three months of storage at 45° C. and in light is equal to 87.5% by weight of the original CBD and CBG in the sample S7.

Further, sample S9 was also prepared with only the same base formula as samples S1-S8 with 99% by weight of the sample S9 and CBD with 1% by weight of the sample S9. The sample S9 was white. The sample S9 was measured using the GC-MS device similar to the measurement of the processed samples S4′ and S7′. The measurement result of the sample S9 is shown as follows.

	Analyte	LOQ (limit of quantitation)	Mass (%)
	THCa	0.08	ND
	Δ9-THC	0.04	ND
	Δ8-THC	0.04	ND
	THCV	0.04	ND
	CBDa	0.08	ND
	CBD	0.04	0.89
	CBDV	0.04	ND
	CBN	0.04	ND
	CBGa	0.08	ND
	CBG	0.04	0.85
	CBC	0.04	ND
	Total	—	0.89

It can be seen from the measurement result of the sample S9, CBD and CBG remained in the white sample S9 is equal to 89% by weight of the original CBD and CBG in the sample S9.

Accordingly, CBD and CBG in the sample S9 are more than CBD and CBG in the processed sample S7′, and CBD and CBG in the processed sample S7′ are more than CBD and CBG in processed S4′, which are consistent with the color checked results in FIGS. 1-7.
